The most natural sentences that occur to me are:
1. I lost my voice singing at a Karaoke night yesterday.
2. I've lost my voice as I went out for Karaoke last night with my colleagues.
---> ...if you have 'lost your voice' it means if you try to talk almost no sound comes out; it is hard for people to hear what you are saying.
3. My throat hurts because I went out for Karaoke last night with my colleagues.
---> ...if your throat hurts then your voice might sound different, or it might hurt to talk, but people can still hear you clearly.
Hope that helps :)
